First check the battery terminals and make sure they are clean and shiny, then use a couble of store bought Alkaline non rechargable batteries and tell me how you get on?

done all that bought new batteries 8 pack and tried your suggestion before I got on line have not had any luck will most likeky have to take it appart and look for a burnt trace or chip was hoping that perhaps there might be something that is known to go bad when this symptom is observed

Sorry stepped away... Fellow ham here, ZL1BTL

It shouldn't be too hard to follow the voltage path using a multimeter until it disappears, but there are a lot of things that an cause the receiver to just stop, in my experience it is unlikely to be the regulator but it is easy enough to check...
